Dynamic Image Key Assignment for Portable Device Attitude
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices, such as cellular telephones, face difficulties in adjusting the image capturing command key based on the user's body attitude, particularly when the device is inclined, making it hard to operate the image capturing command key effectively.
Innovation Solution
Incorporating a determination unit to assess the device's attitude and a setting unit to dynamically assign image capturing command keys based on detected inclination angles, allowing the device to adjust the key's location on the operation unit accordingly, ensuring easy access regardless of the user's holding position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image capturing command key is fixed to a specific key, then the device structure is simple, but the ease of operation deteriorates when the device is held at different angles
Solution Approach 1:
The patent applies the dynamics principle by making the image capturing command key dynamically changeable based on device attitude. The system detects the inclination angle using an inclination angle detection unit and automatically switches between different keys (e.g., first key for 90 degrees clockwise, second key for 90 degrees anti-clockwise) to ensure the command key is always easily accessible regardless of how the user holds the device.
2Adaptability or versatility
If the image capturing command key is fixed to a specific key, then the device complexity is low, but the adaptability to different usage scenarios deteriorates
Solution Approach 1:
The patent applies the parameter changes principle by changing the functional parameter of the command key based on the detected inclination angle. The setting unit modifies which key serves as the image capturing command key according to the device's attitude parameters (e.g., setting first key at corners for 90 degrees clockwise, second key for 90 degrees anti-clockwise), enabling the device to adapt to various holding positions without adding physical complexity.
